Wouldn’t be a shonen without b00bs lol
Yeah, even though the former shoujo mangaka couldn't help but end up with with 5 dudes and 2 girls in the central cast of a shounen manga, she still needed to insert one fanservice scene after 19 chapters! Maybe the editor reminded her of that. I wouldn't say it felt super natural. I haven't as much as checked out the author's older series, so I wouldn't know if Satowa's considerable chest wasn't also only due to this being a shounen manga. I mean, if you compare shoujo and shounen, the shounen genre really emphasizes that body feature.
But then again, absolutely nobody is reading this series for fanservice reasons. In a certain way that makes the rare service all the better, especially if you aren't an art purist.
